刷新页脚到页面底部，推特引导

我通常熟悉使用css刷新页脚的技术。

但是我在将这种方法用于Twitter引导时遇到了一些麻烦，很可能是因为Twitter引导本质上是响应式的。使用Twitter引导，我不能得到页脚冲洗到页面底部使用上述博客文章中描述的方法。

Bootstrap v4+溶液

这里有一个解决方案，不需要重新考虑HTML结构或任何涉及填充的额外CSS技巧:

<html style="height:100%;">
  ...
  <body class="d-flex flex-column h-100">
    ...
    <main class="flex-grow-1">...</main>
    <footer>...</footer>
  </body>
  ...
</html>

请注意，此解决方案允许页脚具有灵活的高度，这在为多个屏幕尺寸设计页面时特别有用，在收缩时使用内容包装。

为什么会这样

style="height:100%;" makes the <html> tag take the whole space of the document. class d-flex sets display:flex to our <body> tag. class flex-column sets flex-direction:column to our <body> tag. Its children (<header>, <main>, <footer> and any other direct child) are now aligned vertically. class h-100 sets height:100% to our <body> tag, meaning it will cover the entire screen vertically. class flex-grow-1 sets flex-grow:1 to our <main>, effectively instructing it to fill any remaining vertical space, thus amounting to the 100% vertical height we set before on our <body> tag.

更简单的官方示例:http://getbootstrap.com/examples/sticky-footer-navbar/

html {
  position: relative;
  min-height: 100%;
}
body {
  margin-bottom: 60px;
}
.footer {
  position: absolute;
  bottom: 0;
  width: 100%;
  height: 60px;
  background-color: #f5f5f5;
}

HTML

<div id="wrapper">

  <div id="content">
    <!-- navbar and containers here -->
  </div>

  <div id="footer">
   <!-- your footer here -->
  </div>

</div>

CSS

html, body {
  height: 100%;
}

#wrapper {
  min-height: 100%;
  position: relative;
}

#content {
  padding-bottom: 100px; /* Height of the footer element */
}

#footer {
  width: 100%;
  height: 100px; /* Adjust to the footer needs */
  position: absolute;
  bottom: 0;
  left: 0;
}

你可以使用jQuery来处理这个问题:

$(function() {
    /**
     * Read the size of the window and reposition the footer at the bottom.
     */
    var stickyFooter = function(){
        var pageHeight = $('html').height();
        var windowHeight = $(window).height();
        var footerHeight = $('footer').outerHeight();

        // A footer with 'fixed-bottom' has the CSS attribute "position: absolute",
        // and thus is outside of its container and counted in $('html').height().
        var totalHeight = $('footer').hasClass('fixed-bottom') ?
            pageHeight + footerHeight : pageHeight;

        // If the window is larger than the content, fix the footer at the bottom.
        if (windowHeight >= totalHeight) {
            return $('footer').addClass('fixed-bottom');
        } else {
            // If the page content is larger than the window, the footer must move.
            return $('footer').removeClass('fixed-bottom');
        }
    };

    // Call when this script is first loaded.
    window.onload = stickyFooter;

    // Call again when the window is resized.
    $(window).resize(function() {
        stickyFooter();
    });
});

使用Bootstrap 3.6.6测试。

HTML

<div class="container footer navbar-fixed-bottom">
  <footer>
    <!-- your footer content here -->
  </footer>
</div>

CSS

.footer {
  bottom: 0;
  position: absolute;
}
